Therefore, each conductive fiber of the electrode part can be connected with the first voltage, so that the emitting end of the electrode part releases an electric field, and the ion release amount is ensured.

Description

Technical Field

[0001] This invention belongs to the field of air conditioner technology, and particularly relates to an air conditioner. Background Technology

[0002] Currently, the indoor unit of an air conditioner has an indoor casing that forms its appearance. The indoor casing is equipped with an air inlet and an air outlet. The air outlet supplies heat-exchange air from the air duct and usually has an electric microparticle water generator installed at the air outlet.

[0003] The charged microparticle water generator includes a high-voltage output component and an electrode component. The high-voltage output component is used to output high-voltage electricity, and the electrode component is used to discharge water at high voltage, causing it to gradually break down into water mist and decompose into highly active nano-sized water ions, which contain a large number of charges and highly active hydroxyl radicals. These ions can decompose and remove bacteria, microorganisms, formaldehyde, VOCs and other components in the air.

[0004] The electrode component is composed of conductive fibers and a cured matrix. The conductive fibers are the conductive matrix and are connected to the high-voltage wire to conduct electrical energy to the emitting tip of the conductive fibers, forming a local high-voltage electric field. The cured matrix plays a role in plastic curing, and the cured matrix is ​​usually an insulator.

[0005] Therefore, if the connection to the high-voltage conductor uses a pointed structure inserted into the axial center of the transmitting electrode, the high resistance of the solidified substrate (reaching over 100,000 ohms in the cross-sectional direction for electrode rods made with ordinary solidified substrates) results in voltage division by the solidified substrate when the conductive fiber electrode skeleton is connected to the pointed structure. This leads to a decrease in voltage (absolute value) in the conductive fiber electrode skeleton further away from the pointed structure, resulting in insufficient effective high-voltage electric field at the end of the transmitting electrode and ultimately insufficient water ion concentration. Therefore, it is urgent to solve the conductivity problem from the center to the edge of the electrode rod, ensuring that the cross-sectional resistance of the electrode rod is less than 1000 ohms.

[0006] In view of the above, this application is hereby submitted. Summary of the Invention

[0007] In this application, terminal blocks are used to connect the electrode component and the voltage output component, and terminal blocks and conductive fiber bundles are used for connection, so that each conductive fiber of the electrode component can be connected to the first voltage, so that the emitting end of the electrode component releases an electric field and ensures the amount of ion released.

[0008] This application provides an air conditioner, which includes:

[0009] The indoor casing has an air inlet and an air outlet.

[0010] A charged microparticle water generator, installed at an air outlet for generating ions, comprises:

[0011] A voltage output component, used to output a first voltage;

[0098] This application discloses an air conditioner 100, with reference to... Figure 1 The air conditioner 100 includes an indoor unit.

[0099] Air conditioner 100 also includes an outdoor unit.

[0100] The outdoor unit is installed outdoors. The indoor and outdoor units are connected by pipes for refrigerant flow.

[0101] The indoor unit includes an indoor housing 1. The indoor housing 1 forms the outer outline of the indoor unit and houses the internal components of the indoor unit.

[0102] An air inlet 2 is formed on the inner shell 1. The air inlet 2 is used to allow indoor air to enter the inner shell 1. The air inlet 2 is equipped with an air inlet grille to filter the air and prevent larger impurities from entering the heat exchange duct.

[0103] An air outlet 3 is formed on the inner shell 1. The air outlet 3 is used to exhaust the air inside the inner shell 1. The indoor air enters the inner shell 1 through the air inlet 2 and is then blown out from the air outlet 3.

[0104] The air outlet 3 can extend along the length of the indoor unit, improving the aesthetics of the indoor unit of the air conditioner 100 and making the indoor unit of the air conditioner 100 more integrated. Of course, in other embodiments of this application, the positions of the air inlet 2 and the air outlet 3 can also be set in other locations, as long as the air intake and exhaust requirements can be met.

[0105] An air guide plate 4 is provided at the air outlet 3. The air guide plate 4 is movably provided at the air outlet 3 and is used to open and close the air outlet 3. When the air outlet 3 is open, the air guide plate 4 can also be configured to guide the heat-exchanged air discharged from the indoor unit through the air outlet 3.

[0106] The indoor casing 1 contains multiple components that constitute a refrigeration cycle or a heating cycle.

[0107] In this application, indoor units include, but are not limited to, wall-mounted air conditioners 100, cabinet air conditioners 100, and ducted air conditioners.

[0108] This application uses a wall-mounted air conditioner 100 as an example for illustration. Other types of air conditioners 100 can have their structural positions adjusted based on the technical solutions of this application. The installation of the charged microparticle water generator 5 is also addressed.

[0109] In some embodiments, the interior housing 1 is generally rectangular in shape.

[0110] The indoor casing 1 includes at least an outer cover. The outer cover forms the basic frame of the air conditioner 100.

[0111] The interior housing 1 also includes a front panel. The front panel is mounted on the front side of the outer casing and forms the front surface of the interior housing 1.

[0112] As can be seen, the front side in this application is Figure 1 The direction indicated by the middle arrow is behind. Figure 1 The direction opposite to the middle arrow.

[0113] It should be noted that the directions described in the text are based on the direction from which the user faces the indoor unit of air conditioner 100. Specifically, the side of the indoor unit of air conditioner 100 facing the user when in use is defined as the front side, and the opposite side is defined as the rear side. The left and right sides are distinguished by the direction from which the user faces the indoor unit of air conditioner 100. The upper and lower sides are defined by the upper and lower sides when the indoor unit of air conditioner 100 is generally working normally.

[0114] The indoor housing 1 also includes a rear panel, which is mounted on the rear side of the outer cover for mounting the air conditioner 100 on the wall of the indoor space.

[0115] The outer casing includes a bottom surface. The bottom surface is configured to define the bottom structure of the air conditioner 100.

[0116] The outer casing includes side panels. The side panels are provided on both sides. They are located on both sides of the bottom surface along the length direction. They are used to form the sides of the air conditioner 100.

[0117] The outer casing includes a top surface. The top surface is configured to define the top appearance of the air conditioner 100.

[0118] In some embodiments, the front surface, top surface, and part of the bottom surface are integrated to facilitate a secure connection with the rear panel and side panels, forming a stable external structure of the air conditioner 100.

[0119] In some embodiments, the rear panel and part of the bottom surface are integrally formed to facilitate a secure connection with other components, forming a stable external structure of the air conditioner 100.

[0120] The indoor unit includes an indoor heat exchanger. The indoor heat exchanger is installed inside the indoor casing 1. The indoor heat exchanger is used to exchange heat with the airflow entering the indoor casing 1.

[0121] The indoor unit includes an indoor fan. The indoor fan is installed inside the indoor casing 1. The indoor fan rotates to allow indoor air to enter the indoor casing 1. After exchanging heat with the indoor heat exchanger, the indoor air flows out of the indoor casing 1.

[0122] The front panel, back panel, bottom surface, top surface, and side panels enclose and form a heat exchange air duct.

[0123] In some embodiments, the indoor fan is configured as a cross-flow fan.

[0124] The inner circumference of the rear panel has space for installing an indoor fan.

[0125] In some embodiments, the indoor heat exchanger is arranged around the indoor fan.

[0126] The air conditioner 100 system in this application includes a compressor that can compress gaseous refrigerant at high temperature and high pressure and discharge the compressed gaseous refrigerant.

[0127] The compressor includes an intake port. Refrigerant flows into the compressor from the intake port to be compressed.

[0128] The compressor includes a discharge port. Refrigerant enters the compressor through the suction port, is compressed by the compressor, and is discharged through the discharge port.

[0129] The air conditioning system 100 includes an indoor heat exchanger for exchanging heat with indoor air.

[0130] The air conditioning system 100 includes an outdoor heat exchanger for exchanging heat with outdoor air.

[0131] The Air Conditioner 100 system also includes a four-way valve. The first port of the four-way valve is connected to the compressor's discharge port. The second port of the four-way valve is connected to the compressor's suction port. The third port of the four-way valve is connected to the indoor heat exchanger. The fourth port of the four-way valve is connected to the outdoor heat exchanger.

[0132] The air conditioning system 100 also includes an electronic expansion valve. The electronic expansion valve is located between the outdoor heat exchanger and the indoor heat exchanger. The electronic expansion valve is used for throttling. It expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant.

[0133] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger functions as a condenser, the air conditioner 100 functions as a heater in heating mode. When the indoor heat exchanger functions as an evaporator, the air conditioner 100 functions as a cooler in cooling mode.

[0134] Multi-split air conditioners 100 use refrigerant flow to blow out air that is higher or lower than the indoor temperature, or the same as the indoor temperature, in order to adjust the temperature and humidity of the indoor environment; or they use the speed of the indoor fan to adjust the airflow speed of the indoor environment.

[0135] When the air conditioner is running in cooling mode, the refrigerant from the compressor condenses in the outdoor heat exchanger. The condensed refrigerant then expands through the electronic expansion valve. The expanded condensate evaporates in the indoor heat exchanger. Finally, the evaporated refrigerant circulates back into the compressor.

[0136] When the air conditioner is operating at 100°C for heating, the refrigerant from the compressor flows through the indoor heat exchanger and condenses. The condensed refrigerant then expands by passing through the electronic expansion valve. The expanded condensate evaporates through the outdoor heat exchanger. The evaporated refrigerant then circulates back to the compressor.

[0137] Reference Figure 2 The indoor unit also includes a charged microparticle water generator 5, which is installed at the air outlet 3 to generate ions with sterilization and deodorization effects. The generated ions are directly blown into the room, improving the air purification effect.

[0138] In some embodiments, refer to Figure 3 The charged microparticle water generator 5 includes a voltage output component 51. The voltage output component 51 is used to output a stable first voltage to ensure the stability and quantity of ions released by the charged microparticle water generator 5.

[0139] The charged microparticle water generator 5 includes an electrode component 52. The electrode component 52 is used to absorb moisture from the air and release ions using a received first voltage.

[0140] In some embodiments, the charged microparticle water generator 5 is installed at the air outlet 3. At least the electrode component 52 is installed at the air outlet 3 so that the ions generated by the electrode component 52 can enter the room with the airflow from the air outlet 3.

[0141] In some embodiments, the electrode component 52 includes a cured substrate 521.

[0142] In some embodiments, the cured matrix 521 may be composed of a crosslinking agent and an initiator in a certain proportion.

[0143] In the above, the crosslinking agent is a substance that can act as a bridging link during the condensation of linear molecular structures, causing the groups in the molecules to bond together and form an insoluble and infusible network.

[0144] An initiator is a substance that can initiate the polymerization reaction of monomers. Unsaturated monomer polymerization active centers include free radicals, anionic compounds, cationic compounds, and coordination compounds. In the adhesive industry, the free radical type is the most widely used. It exhibits unique chemical activity, undergoing homolytic cleavage of covalent bonds under the influence of heat or light to generate two free radicals, which can initiate polymerization reactions.

[0145] In some embodiments, a crosslinking agent is first added to a mold to allow a crosslinking reaction to occur and form a crosslinked structure; then an initiator is added to initiate a monomer polymerization reaction, causing the monomers in the crosslinked structure to polymerize, ultimately obtaining a polymer material with a crosslinked structure.

[0146] The electrode component 52 includes conductive fibers 522. The conductive fibers 522 are capable of conducting electricity, and a local electric field is formed at the ends of the conductive fibers 522.

[0147] A plurality of conductive fibers 522 are disposed within the cured substrate 521. The cured substrate 521 and the conductive fibers 522 constitute the main structure of the electrode component 52.

[0148] In some embodiments, the emitting tip of the conductive fiber 522 extends to the outside of the cured substrate 521, so that one end of the electrode component 52 forms an emitting tip with an exposed multifiber structure.

[0149] In this embodiment, the conductive fiber 522 is formed into a rod-shaped structure using the cured substrate 521. In some embodiments, the main structure formed by the conductive fiber 522 and the cured substrate 521 can also be configured as a cylindrical structure, a cubic column structure, or a flat sheet structure. It should be noted that the structure of the main structure only needs to satisfy the requirement of connecting the first voltage and generating an electric field at the transmitting end.

[0150] In some embodiments, the electrode component 52 may be configured as a solid structure. In some embodiments, the electrode component 52 may also be configured as a cylindrical structure, a hollow structure, or a mesh structure, etc.

[0151] In some embodiments, conductive fibers 522 are installed in a certain regular pattern within the cured substrate 521 and together with the cured substrate 521 form the main structure of the electrode component 52.

[0152] In some embodiments, conductive fibers 522 are distributed inside and on the outer surface of the cured substrate 521.

[0153] In some embodiments, the conductive fiber 522 is configured as carbon fiber.

[0154] Carbon fiber is a fiber composed of carbon atoms, and like metals, it has excellent electrical conductivity. It can rapidly transfer electrons even at low voltages. Furthermore, carbon fiber possesses very high strength and stiffness per unit mass or unit volume. The diameter of carbon fiber bundles can range from a few micrometers to tens of micrometers, achieving a curvature radius that is one-tenth or even one-hundredth that of pointed structures.

[0155] Compared to pointed electrodes, carbon fiber can generate a stronger local electric field under the same supply voltage and frequency conditions, ionizing to produce a higher concentration of negative air ions or water ions.

[0156] In this embodiment, unidirectional carbon fiber is used as the conductive fiber 522. Choosing this carbon structure as the conductive framework can induce an increase in the unidirectional electron migration activity of the electrode, thereby promoting an increase in the unidirectional negative ion yield.

[0157] Carbon fiber is subjected to tensile force during the production process, causing its structure to become oriented, thus exhibiting anisotropy in mechanical and electrical properties.

[0158] In some embodiments, the diameter of the electrode component 52 is larger than the diameter of the conductive fiber 522. The number of conductive fibers 522 is configured to be N, and the diameter of the conductive fiber 522 is y. Wherein, N≥100, and y<0.2mm.

[0159] This configuration results in a large number of conductive fibers 522 with small diameters, making the electric field generated by the electrode component 52 equivalent to the superposition of multiple localized small electric fields to form a larger electric field. This significantly increases the concentration of negative air ions and enhances the release capacity of negative ions.

[0160] Simultaneously, the repulsion between ions due to their shared charge enhances the diffusion capacity of negative ions in space, increasing their spatial diffusion range. This also reduces the reliance on auxiliary devices such as fans during the application of the charged microparticle water generator 5. (Refer to...) Figure 4 The diagram shows the effective electric field of a single tip and multiple tips discharge.

[0161] In some embodiments, carbon fibers are used as electrode materials in carbon fiber bundles ranging from 1 to 10 micrometers. A fiber bundle in an electrode component 52 contains N carbon fibers, forming a multi-point discharge electric field. Here, N is less than 500,000.

[0162] If the number of carbon fibers is too large, the overall size of the electrode component 52 will be too large, making it difficult to install the charged microparticle water generator 5. Therefore, the number of carbon fibers should be less than 500,000.

[0163] Therefore, the electrode component 52 in this embodiment is equivalent to a superposition of multiple tip discharge electrodes, and its effective electric field strength and range are several times, hundreds of times or even thousands of times that of a single tip discharge electrode.

[0164] The cured substrate 521 and conductive fibers 522 together form the main body of the electrode component 52. The emission tips of several conductive fibers 522 extend to the outside of the cured substrate 521.

[0165] In some embodiments, refer to Figure 5-6 The conductive fiber 522 and the cured substrate 521 together form a rod shape, and the top of the electrode rod has a conductive fiber bundle exposed. The height of the exposed conductive fiber bundle is defined as h, where 0.01mm≤h.

[0166] To ensure an effective electric field is generated at the electrode tip, conductive fiber bundles are exposed at the tip of the electrode rod. The minimum exposed conductive fiber bundle is 0.01 mm, so that the electrode component 52 can generate an effective electric field for negative air ions or water ions.

[0167] In some embodiments, a conductive fiber bundle is exposed at the top of the electrode rod, and the height of the exposed conductive fiber bundle is defined as h, where h ≤ 10 mm.

[0168] In this embodiment, the height of the exposed conductive fiber bundle should not be too large. When the height is too large, multiple conductive fibers 522 will overlap, entangle, or have inconsistent directions, which will affect the formation of the electric field.

[0169] Meanwhile, in this embodiment, the important source of the ionized target product, water ions, is water. This water comes partly from the air, but more significantly from the supply to the tip electric field from inside the electrode component 52. The moisture inside the electrode component 52 can be guided to the end of the conductive fiber 522 through internal channels, acting similarly to a capillary. This moisture is used to generate water ions using the first voltage. To ensure a sufficient supply of moisture, the exposed height of the conductive fiber 522 should not be too high. Therefore, the exposed height h of the conductive fiber 522 is set to be less than 10 mm.

[0170] In some embodiments, the proportion of the number n of conductive fibers 522 exposed to the cured substrate 521 to the total number of conductive fibers 522 is defined as X, where X is greater than 1%, so that the discharge effect of the electrode component 52 is at least higher than that of the pointed structure electrode in the relative art.

[0171] While the ideal situation is for all conductive fibers 522 to be exposed, which would produce the best superimposed electric field effect, operations during the manufacturing process, such as mold forming, fiber bundle cutting, and filling of the cured substrate 521, may result in some conductive fibers 522 not being exposed. This will negatively impact the creation of the superimposed electric field. However, at least 1% of the conductive fibers 522 should be exposed in the cured substrate 521 to ensure the discharge effect of the electrode component 52.

[0172] In some embodiments, refer to Figure 5 The diameter of the bottom of the electrode component 52 is defined as d, and the radius of curvature of the arc formed by a plurality of conductive fibers 522 is d / 2, so that when the electrode component 52 is connected to the voltage output component 51, the transmitting end generates an electric field to ionize the moisture in the air absorbed by the water-absorbing material 523.

[0173] In some embodiments, d ≥ 1 mm. If the diameter of the electrode component 52 is too small, the number of conductive fibers 522 will be insufficient, resulting in insufficient electric field strength generated by the electrode component 52, which in turn leads to a small amount of ions generated by the charged microparticle water generator 5 and a reduced cleaning effect.

[0174] In some embodiments, d ≤ 6 mm. If the diameter of the electrode component 52 is too large, the overall size of the charged microparticle water generator 5 becomes too large, increasing the difficulty of installation.

[0175] In some embodiments, the top of the electrode component 52 may be shaped, but is not limited to, a bun shape or a platform shape.

[0176] In some embodiments, the conductive fiber 522 may be a metal fiber.

[0177] In some embodiments, the conductive fiber 522 may be designed using a combination of polymer and metal salt to achieve good conductivity after absorbing moisture, or other design methods that can achieve good conductivity after absorbing moisture.

[0178] In some embodiments, the polymer includes polyethylene, polypropylene, etc. Metal salts include LiCl, CaCl2, NaCl, etc.

[0179] In some embodiments, the electrode component 52 further includes a water-absorbing material 523. The water-absorbing material 523 is disposed at least on the surface of the electrode component 52 to capture moisture in the air and for use in electrode ionization.

[0180] In some embodiments, the absorbent material 523 is composed of MOFs. MOFs have the advantages of high specific surface area and high active sites, and by setting the ligand design of MOFs, they can have higher moisture absorption performance under low humidity conditions. This enables the electrode component 52 to stably release ions in low humidity environments.

[0181] In some embodiments, the content of MOFs in the absorbent material 523 is greater than a first parameter, wherein the first parameter is set to 1%. While the structure of MOFs is conducive to moisture collection, their rigid structure is not conducive to large-scale moisture storage. When the MOF content is too low, the composite material has poor adsorption capacity for moisture in the air.

[0182] In some embodiments, the content of MOFs in the absorbent material 523 is less than the second parameter, wherein the second parameter is set to 2.2%. When the MOF content is too high, the aggregation phenomenon and the rigid structure of MOFs cause moisture to concentrate in the MOF voids. The moisture cannot be transported and stored in the surrounding water storage structure 526 in time, thus resulting in a decrease in moisture absorption capacity and a decrease in the water conductivity of the electrode structure, making it impossible to efficiently transport the absorbed moisture to the end of the electrode structure for ionization.

[0183] Reference Figure 9 The figure illustrates the moisture absorption performance of the water-absorbing material 523 over 24 hours when the MOFs doping content is different. As shown in the figure, the moisture absorption performance of the electrode is better when the MOFs doping content is 1.1% to 2.9% than when the content is 0% to 1%.

[0184] In some embodiments, the content of MOFs in the absorbent material 523 is 1.1%.

[0185] In some embodiments, the content of MOFs in the absorbent material 523 is 2%.

[0186] Reference Figure 8 The figure shows a comparison of the water absorption rates of the electrode component 52, sample 1, and sample 2 after being placed continuously for 24 hours in an environment with a humidity of 30% RH and a temperature of 25°C. The electrode component 52 in this application includes conductive fibers 522 and a cured substrate 521, wherein the cured substrate 521 is doped with MOFs. Sample 1 consists of conductive fibers 522 and a cured substrate 521, without MOFs doping. Sample 2 is formed by molding the cured substrate 521 and is without MOFs doping.

[0187] As shown in the figure, the electrode component 52 in this application has the best moisture absorption performance, with a moisture absorption rate of 0.17 g·g-1 after 24 hours, and still has the ability to continue to absorb moisture. This indicates that a water storage structure 526 has been successfully formed inside the solidified substrate 521, and that moisture in the air can be captured by the moisture-absorbing functional material and continuously transported to the water storage structure 526 through the micropores.

[0188] As time goes by, the moisture in the air is gradually absorbed into the electrode structure. As the water storage capacity inside the water storage structure 526 gradually reaches saturation, the absorption rate gradually slows down, but it still has not reached saturation after 24 hours.

[0189] Because a small amount of cured matrix 521 was added around the conductive fiber 522 and there were no moisture-absorbing materials such as MOFs, Sample 1 could only absorb water by relying on the water storage structure 526 and micropores generated in the small amount of cured matrix 521. Its moisture absorption performance was very limited, with a saturation moisture absorption rate of only 0.013 g·g-1, and it reached saturation in 6 hours.

[0190] No moisture-absorbing material was added to the electrode component 52 of sample 2. It relies on the surface micropores 525 and the internal water storage structure 526 to absorb and store water. The moisture absorption rate reached 0.09 g g⁻¹ in 24 hours, and it still has a weak ability to continue to absorb moisture. It can be judged that its internal water storage structure 526 is not completely saturated at this time. However, due to the lack of efficient ability to capture air moisture, its moisture absorption rate in 24 hours is almost only half of that in the technical solution of this embodiment.

[0191] In some embodiments, refer to Figure 7 The electrode component 52 includes a water storage structure 526. The water storage structure 526 is disposed within the solidified substrate 521. The water storage structure 526 consists of micron-sized pores created within the solidified substrate 521 during the fabrication of the electrode component 52 due to lateral expansion and stretching. When the moisture-absorbing material becomes saturated with moisture captured from the air, the moisture is stored in these pores in the form of liquid water.

[0192] In some embodiments, the water storage structure 526 is a three-dimensional network structure, and the water storage structure 526 is set at the micrometer level to store absorbed water, and can repeatedly absorb and dehydrate without damaging its own structure.

[0193] In some embodiments, the size of the water storage structure 526 is between a few micrometers and tens of micrometers, which can guide external water into the interior of the water storage structure 526 through surface tension and capillary action, and prevent internal water from flowing out due to gravity.

[0194] In some embodiments, the electrode component 52 mainly consists of conductive fibers 522 and a solidified substrate 521. The conductive fibers 522 conduct electricity longitudinally, forming a local electric field at their ends. Due to a special manufacturing process, the electrode component 52 undergoes lateral expansion and stretching, creating micron-sized pores, i.e., water storage structures 526, within the solidified substrate 521 between the conductive fibers 522.

[0195] In some embodiments, the electrode component 52 includes surface micropores 525, which are used to connect the water-absorbing material 523 and the water storage structure 526, and to conduct water in the air captured by the water-absorbing material 523 to the water storage structure 526 for storage.

[0196] In some embodiments, refer to Figure 36 The surface micropores 525 are configured as the surface of the electrode structure. Moisture on the surface can be transferred to the interior of the electrode component 52 through the surface micropores 525 and stored in the water storage structure 526.

[0197] In some embodiments, the electrode component 52 includes a water channel 524. The water channel 524 is disposed inside the electrode component 52. The water channel 524 is located between the cured substrate 521 and the conductive fiber 522. The water channel 524 is configured as an elongated channel with a width on the order of micrometers extending along the surface of the conductive fiber 522.

[0198] The water-conducting channels 524 in the solidified matrix 521 material can improve the dispersion of MOFs in the electrode and reduce the performance degradation caused by MOF agglomeration.

[0199] The water channel 524 is connected to the water storage structure 526. After the electrode component 52 is connected to the first voltage, the water at the end of the electrode component 52 is ionized to generate water ions, consuming the water at the end of the electrode component 52. At this time, the water stored in the electrode component 52 can be transported to the end of the electrode component 52 through the water channel 524 for ionization to generate water ions.

[0200] By setting a water channel 524 in the electrode component 52, the water supply to the emitting end of the electrode component 52 during the generation of water ions is realized, while limiting unnecessary water loss.

[0201] The water channel 524 can assist in the storage and transportation of water. Water molecules are affected by surface tension and capillary action in the water channel 524, which makes the water form a stable water column in the water channel 524 and prevents the water from flowing due to gravity.

[0202] In this embodiment, there are micron-sized water storage structures 526 between the conductive fibers 522. The water storage structures 526 are connected to the surface micropores 525, which is beneficial for water storage in the electrode component 52. The water storage structures 526 are connected to the conductive fibers 522, which can conduct water along the conductive fibers 522 to the emitting tip of the conductive fibers 522.

[0203] By incorporating the water-absorbing material 523, the water storage structure 526, and the water guiding channel 524 in a coordinated manner, the water absorption, storage, and guiding capabilities of the electrode component 52 are effectively improved. This eliminates the need for other semiconductor cooling devices, resulting in a lower failure rate compared to related technologies. Furthermore, this charged microparticle water generator 5 operates within a wider humidity range, functioning even at humidity levels above 20%, thus broadening the applicability of the air conditioner 100 indoor unit and enhancing the overall competitiveness of the unit.

[0204] In some embodiments, refer to Figure 7 The absorbent material 523 is dispersed within the solidified matrix 521. The absorbent material on the outer surface of the electrode component 52 comes into contact with air, utilizing its highly active sites to efficiently capture water molecules from the air, achieving efficient moisture absorption. The absorbent material located inside the electrode component 52 has the function of retaining moisture.

[0205] Water-absorbing material 523 is incorporated into the cured matrix 521. The introduction of water-absorbing material 523 allows it to absorb moisture from the air in low-humidity environments, providing a moisture source for the ionization of conductive fibers 522.

[0206] In some embodiments, when the water-absorbing material 523 is incorporated into the cured matrix 521, the organic ligand can form hydrogen bonds with the cured matrix 521 material, thereby achieving uniform dispersion and thus achieving the uniformity of the overall material properties.

[0207] In addition, the introduction of water-absorbing material 523 can form a heterostructure with the solidified matrix 521 material, change the energy band structure of the material, improve the water utilization efficiency of electrode component 52, and thus improve the negative ion yield.

[0208] Reference Figure 10 The figure shows a comparison of the internal cross-sectional infrared spectral analysis of the electrode component 52, sample 1, and sample 2 in this application. The electrode component 52 in this application includes conductive fibers 522 and a cured substrate 521, wherein the cured substrate 521 is doped with MOFs. Sample 1 consists of conductive fibers 522 and a cured substrate 521, without MOF doping. Sample 2 is formed by bonding the cured substrate 521 and is also without MOF doping.

[0209] As shown in Figures (a) and (b) below, no infrared characteristic peaks of functional groups were detected in sample 1, indicating that sample 1 is mainly made of carbon fiber. However, in sample 2, the 400cm² peak...-1 Up to 1800cm -1 The series of peaks at this location are mainly stretching vibration peaks of functional groups carried by the adhesive. In this embodiment, the electrode component 52 at 3400 cm⁻¹... -1 A distinct hydroxyl vibration peak appears at this location.

[0210] In this embodiment, the hydroxyl groups in the electrode component 52 mainly originate from the surface hydroxylation during the carbon fiber pretreatment and the hydration network adhesive process. The introduction of hydroxyl groups can greatly improve the hydrophilicity of the material and enhance its water absorption performance.

[0211] The XRD characterization is shown in Figure (c). Characteristic diffraction peaks corresponding to MOF were found in the electrode component 52 in this embodiment. However, since the MOF material is encapsulated in the gel network, other peaks are not obvious. This also effectively indicates that it is a composite material composed of carbon fiber + MOF + solidified matrix 521. Sample 1 is basically similar to the carbon fiber substrate because Sample 1 is formed by sintering and extruding the outer layer of carbon fiber.

[0212] In some embodiments, within a certain humidity range, water in the air is captured by the water-absorbing material 523 incorporated into the cured matrix 521 and enters the surface micropores 525, and then introduced into the water storage structure 526. When the electrode component 52 and the voltage output component 51 are connected, the emitting tip of the conductive fiber 522 ionizes the water to generate water ions, thereby consuming the water at the emitting end of the electrode component 52, and a pressure difference is formed between the emitting end and the bottom end of the electrode component 52.

[0213] The water in the water storage structure 526 is transported to the emitting end of the electrode component 52 through the water guiding channel 524 to replenish the water required for ionization.

[0214] In some embodiments, once the absorbent material 523 is saturated with moisture captured from the air, the moisture is stored in the pores as liquid water. This can further improve the moisture absorption characteristics of the electrode component 52, achieving a moisture absorption characteristic greater than 10% of the mass of the electrode component 52, even in a dry environment with an ambient humidity of 30% RH.

[0215] Moisture stored inside electrode component 52 can diffuse longitudinally along conductive fiber 522. Under the influence of an electric field, the emitting tip of conductive fiber 522 generates a local electric field with the air, and water molecules on the surface of the emitting tip of conductive fiber 522 are ionized into hydroxyl radicals under the influence of the electric field. At the same time, electrons released by the negative high-voltage electrode form negative ions with the air around the electric field. Hydroxyl radicals and negative ions are encapsulated by high-voltage atomized nano-water particles and diffuse into the air.

[0216] The moisture inside the electrode component 52 continuously supplies water ions to the emitting tip of the conductive fiber 522, while the water-absorbing material 523 on the surface of the solidified substrate 521 captures moisture from the air to replenish the moisture of the electrode component 52, forming a moisture replenishment and consumption cycle.

[0217] In some embodiments, the electrode component 52 includes an absorbent material 523. (See reference...) Figure 11 The absorbent material 523 is combined with the conductive fiber 522. The absorbent material 523 is attached to the conductive fiber 522. The absorbent material 523 located on the conductive fiber 522 on the outer surface of the cured substrate 521 comes into contact with the air and captures moisture from the air by utilizing its highly active sites, achieving a highly efficient moisture absorption effect.

[0218] In some embodiments, attaching MOFS to conductive fiber 522 using a special process can enhance the hydrophilicity of the surface of conductive fiber 522, which will greatly enhance the hydrophilicity of the water channel 524 located on the surface of conductive fiber 522, thereby greatly improving the water transport performance within the water channel 524.

[0219] In some embodiments, within a certain humidity range, moisture in the air is captured by the water-absorbing material 523 on the conductive fiber 522 and then introduced into the surface micropores 525 and into the water storage structure 526.

[0220] When the electrode component 52 and the voltage output component 51 are connected, the emitting tip of the conductive fiber 522 ionizes the water to generate water ions, thereby consuming the water at the emitting end of the electrode component 52, and a pressure difference is formed between the emitting end and the bottom end of the electrode component 52.

[0221] The water in the water storage structure 526 is transported to the emitting end of the electrode component 52 through the water guiding channel 524 to replenish the water required for ionization.

[0222] In some embodiments, within a certain humidity range, moisture in the air is captured by the water-absorbing material 523 on the conductive fiber 522, enters the surface micropores 525, and is then introduced into the water channel 524.

[0223] When the electrode component 52 and the voltage output component 51 are connected, the emitting tip of the conductive fiber 522 ionizes the water to generate water ions, thereby consuming the water at the emitting end of the electrode component 52, and a pressure difference is formed between the emitting end and the bottom end of the electrode component 52.

[0224] The water in the water channel 524 is directly transported to the emitting end of the electrode component 52 to replenish the water required for ionization.

[0225] In some embodiments, once the absorbent material 523 is saturated with moisture captured from the air, the moisture is stored in the pores as liquid water. This further improves the moisture absorption characteristics of the electrode component 52, achieving a moisture absorption characteristic greater than 10% of the mass of the electrode component 52, even in a dry environment with an ambient humidity of 30% RH.

[0226] Moisture stored inside electrode component 52 can diffuse longitudinally along conductive fiber 522. Under the influence of an electric field, the emitting tip of conductive fiber 522 generates a local electric field with the air, and water molecules on the surface of the emitting tip of conductive fiber 522 are ionized into hydroxyl radicals under the influence of the electric field. At the same time, electrons released by the negative high-voltage electrode form negative ions with the air around the electric field. Hydroxyl radicals and negative ions are encapsulated by high-voltage atomized nano-water particles and diffuse into the air.

[0227] The moisture inside the electrode component 52 continuously supplies water ions to the emitting tip of the conductive fiber 522, while the water-absorbing material 523 on the surface of the conductive fiber 522 captures moisture from the air to replenish the electrode component 52, forming a water supply and consumption cycle.

[0228] When the voltage output component 51 does not supply power to the electrode component 52, the charged microparticle water generator 5 is in a condensed state. The water-absorbing material 523 of the electrode component 52 can adsorb moisture in the air onto the surface of the electrode component 52. Utilizing the pore structure of the transverse pores and the high specific surface area, water molecules on the surface of the electrode component 52 can be stored inside the electrode component 52 using the capillary principle.

[0229] When the voltage output component 51 supplies power to the electrode component 52, the charged microparticle water generator 5 releases ions. Specifically, refer to... Figure 12 The conductive fiber 522 generates a negative high-voltage electric field at its emitting tip. The moisture inside the electrode component 52 is atomized by high pressure and released through the transverse and longitudinal pores, and is ionized into hydroxyl radicals. At the same time, the electrode released by the electrode component 52 forms negative ions with the air around the negative high-voltage electric field. The hydroxyl radicals and negative ions are wrapped by the high-pressure atomized nano water ions and diffuse into the air.

[0230] In other words, some of the water inside electrode component 52 is excited by a negative high-voltage electric field to become hydroxyl radicals, which are then encapsulated by water particles to form hydroxyl-charged microparticle water. Electrons released from electrode component 52 react with oxygen (O2) in the air to generate negative ions (O2-), which are then encapsulated by water particles to form negative ion (O2-) charged microparticle water. Both hydroxyl radicals and negative ion (O2-) charged microparticle water have bactericidal and deodorizing air purification effects, and because the outer layer is encapsulated by nanoparticles, they have a longer range of action and better efficacy.

[0231] When the first voltage is used to supply power to the electrode component 52, the water-absorbing material 523 can also absorb moisture from the air and generate charged microparticle water through the same path.

[0232] After ionization at the discharge tip of the conductive fiber 522, the water is consumed. Utilizing the pressure difference between the interior and tip of the conductive fiber 522, water inside the conductive fiber 522 can be absorbed to the discharge tip for continuous ionization. This ensures a continuous water supply to the electrode component 52 and allows for its storage, eliminating the cumbersome process of periodically adding water to the water storage component in related technologies. It also avoids the drawbacks of obtaining condensate through structural loads and costly semiconductor cooling modules in related technologies.

[0233] The indoor unit provided in this embodiment has an air purification function. By installing the charged microparticle water generator 5 at the air outlet 3, the charged microparticle water generated by it is directly blown into the room, thereby improving the air purification effect.

[0234] refer to Figure 35 The charged microparticle water generator 5 also includes a base 53. The end of the electrode component 52 furthest from the emitting tip is mounted on the base 53. The base 53 has a through hole 531 for a high-voltage wire 60 to pass through. The voltage output component 51 is connected to the electrode component 52 through the high-voltage wire 60 passing through the through hole 531. The base 53 serves to mount and support the electrode component 52, and the base 53 is made of insulating material.

[0235] In some embodiments, the base 53 is installed at the air outlet 3 of the indoor unit.

[0236] In this embodiment, the electrode component 52 and the voltage output component 51 are separate structures, connected by a high-voltage wire 60. Of course, in some other embodiments, the base 53 can be integrally connected to the voltage output component 51. This arrangement shortens the distance of the high-voltage wire 60 between the electrode component 52 and the voltage output component 51, and reduces the size of the charged microparticle water generator 5, facilitating installation.

[0237] Specifically, in this embodiment, the base 53 is hollow inside and has an open bottom, and a through hole 531 is provided at the top of the base 53. The through hole 531 protrudes from the top of the base 53 to facilitate connection with the electrode component 52.

[0238] Further reference Figure 14 The charged microparticle water generator 5 also includes a connecting cover 54, which is mounted on the base 53. A mounting position 541 for mounting and fixing the electrode component 52 is formed on the side of the connecting cover 54 away from the base 53. The mounting position 541 is opposite to and communicates with the through hole 531.

[0239] Specifically, in this embodiment, the connecting cover 54 is hollow and has an opening, the mounting position 541 protrudes from the connecting cover 54 and is disposed opposite to the through hole 531, and the through hole 531 extends into the mounting position 541.

[0240] In order to achieve a detachable connection between the connecting cover 54 and the base 53, a connecting groove 56 is provided on the inner side wall of the connecting cover 54, and a buckle 55 is provided on the outer wall of the base 53. The buckle 55 and the connecting groove 56 are adapted to connect and fix the connecting cover 54 and the base 53, which is simple and convenient.

[0241] Furthermore, refer to Figure 13 In order to realize the installation of the charged microparticle water generator 5, the charged microparticle water generator 5 also includes a mounting plate 57, which is connected to the connecting cover 54, and the mounting plate 57 is suitable for installation on the indoor housing 1 and located at the air outlet 3.

[0242] To enhance the release capacity of the charged microparticle water generator 5, one or more electrode components 52 may be configured to improve the release capacity of negative ions. Multiple electrode components 52 may be connected in parallel. For example... Figure 2 As shown, there are two electrode components 52. Correspondingly, the number of through holes 531 on the base 53 and the number of mounting positions 541 on the connecting cover 54 are the same as the number of electrode components 52.

[0243] In some embodiments, the air guide plate 4 is movably disposed at the air outlet 3 to open or close the air outlet 3. When the air guide plate 4 opens the air outlet 3, the air guide plate 4 can also be used to guide the heat-exchanged air discharged from the indoor unit through the air outlet 3.

[0244] In some embodiments, the indoor unit further includes multiple air guide vanes. These multiple air guide vanes are oscillatingly disposed within the air outlet 3 along the length of the housing, and are spaced apart along the length of the housing. By providing multiple air guide vanes, the airflow direction at the air outlet 3 can be adjusted, thereby dispersing and guiding the airflow blown out of the air outlet 3, and thus blowing ions to a designated area for diffusion. This also improves the comfort and uniformity of the airflow.

[0245] In some embodiments, a plurality of conductive fibers 522 are dispersedly disposed at one end of the cured substrate 521 so that the electrode component 52 forms an emitting end with exposed conductive fibers 522. The outer edge of the emitting end is configured as an arc-shaped structure.

[0246] When the indoor unit is in normal use, the airflow after heat exchange passes through the charged microparticle water generator 5 and is blown out through the air outlet 3. The heat-exchanged air can carry ions out, which can facilitate the blowing out of negative ions and also blow the ions further.

[0247] Ions diffuse into the indoor space under the influence of electric field force and heat exchange airflow, colliding and combining with bacteria and viruses in the indoor space. They destroy cell protein structure to kill bacteria and inactivate viruses. At the same time, negatively charged ions can combine with positively charged particulate matter suspended in the indoor space and settle down, thus purifying the air and keeping the indoor air fresh and clean.

[0248] In some embodiments, the indoor fan operates in reverse, and indoor air can enter the interior of the housing from the opening and closing of the air outlet 3 and the air guide plate 4, and flow through the charged microparticle water generator 5. Under the action of electric field force and indoor air flow force, ions diffuse into the interior space of the housing and come into full contact with the indoor heat exchanger, indoor fan, etc. Negative ions collide and combine with bacteria and viruses attached to their surfaces, thereby killing bacteria and inactivating viruses by destroying the bacterial protein structure.

[0249] In some embodiments, the electrode component 52 is composed of conductive fibers 522 and a cured substrate 521. The conductive fibers 522 are used to connect with the high-voltage wire 60 to conduct electrical energy to the ends of the conductive fibers 522, forming a local electric field. The cured substrate 521 serves to shape and cure the material.

[0250] In some embodiments, the cured substrate 521 is an insulator. In this case, it is necessary to ensure that each conductive fiber 522 is effectively electrically connected to the high-voltage wire 60 to ensure the superposition of the electric field at the end of the conductive fiber 522, and to ensure the ion release amount and ion release stability of the electrode component 52.

[0251] However, due to the fineness of the conductive fiber 522, it is not feasible to effectively connect each conductive fiber 522 to the high-voltage wire 60 in actual operation.

[0252] To ensure a stable connection between the conductive fiber 522 and the first voltage, in some embodiments, the charged microparticle water generator 5 includes a conductive structure 58. The conductive structure 58 is disposed between the electrode component 52 and the voltage output component 51 for delivering the first voltage to the conductive fiber 522.

[0253] In some embodiments, refer to Figure 15 The conductive structure 58 includes several terminals 581. One end of the terminal 581 is electrically connected to the high-voltage wire 60 of the voltage output component 51. Multiple conductive fibers 522 form a conductive fiber bundle, and the conductive fiber bundle is correspondingly connected to the other end of a terminal 581.

[0254] When the voltage output component 51 outputs a first voltage to the electrode component 52, the first voltage is transmitted to a plurality of conductive fibers 522 through the high voltage wire 60 and the terminal 581 to form an electric field at the emitting end of the electrode component 52, and the electric field is used to ionize the moisture in the air absorbed by the water-absorbing material 523.

[0255] In some embodiments, a plurality of conductive fibers 522 are divided into multiple conductive fiber bundles, and the conductive fiber bundles are connected one-to-one with the terminals 581.

[0256] When the voltage output component 51 outputs a first voltage to the electrode component 52, the first voltage is transmitted to a plurality of conductive fibers 522 through the high voltage wire 60 and the terminal 581 to form an electric field at the emitting end of the electrode component 52; and the electric field is used to ionize the moisture in the air absorbed by the water-absorbing material 523.

[0257] In some embodiments, the cured substrate 521 includes a plurality of conductive components, which are dispersed within the cured substrate 521 to achieve conductivity of the cured substrate 521.

[0258] In some embodiments, refer to Figure 16 One end of the conductive structure 58 is connected to the voltage output component 51, and the other end of the conductive component is partially or completely submerged in the cured substrate 521, so that the conductive structure 58 is in contact with the cured substrate 521 and part of the conductive fiber 522, so that the first voltage is delivered to the conductive fiber 522.

[0259] The conductive fiber 522 connected to the conductive structure 58 is defined as the first conductive fiber 5221, and the conductive fiber 522 that is not in direct contact with the conductive structure 58 is defined as the second conductive fiber 5222.

[0260] When the voltage output component 51 outputs the first voltage to the electrode component 52, the first voltage is directly transmitted to the first conductive fiber 5221 through the conductive structure 58.

[0261] A momentary potential difference is formed between the first conductive fiber 5221 and the second conductive fiber 5222. Under the action of the conductive structure 58, a current is formed in the solidified substrate 521, so that a circuit connection is formed between the first conductive fiber 5221 and the second conductive fiber 5222.

[0262] A first voltage is connected to the first conductive fiber 5221 and the second conductive fiber 5222 to form an electric field at the emitting end of the electrode component 52 and ionize the moisture in the air absorbed by the electrode component 52.

[0263] If the resistance of the cured substrate 521 is too high, for example, the cross-sectional resistance of the electrode structure prepared by ordinary cured substrate 521 reaches more than 100,000 ohms. When the conductive fiber 522 is connected to the pointed structure, it will be divided by the cured substrate 521. As a result, the voltage value of the conductive fiber 522 will be lower the farther away from the pointed structure, resulting in insufficient electric field at the emission tip of the conductive fiber 522 and ultimately insufficient water ion concentration.

[0264] In some embodiments, the conductive component is a conductive ion 528.

[0265] In some embodiments, the conductive ions 528 are introduced by adding an alkaline solvent during the preparation of the cured substrate 521. For example, the alkaline solvent can be potassium hydroxide or sodium hydroxide.

[0266] This allows the cured substrate 521 to conduct electricity through the coordinated action between the conductive ions 528 (representing potassium or sodium ions) and the carbon fibers after energization, effectively reducing the cross-sectional resistance of the cured substrate 521 and improving its conductivity.

[0267] In some embodiments, the preparation process of the cured substrate 521 is as follows: polyacrylic acid is dissolved in deionized water, and the pH value is adjusted to between 6 and 8 using an alkaline reagent (optionally KOH, NaOH, etc.), followed by the addition of a crosslinking agent and an initiator. The added alkaline reagent, such as KOH, not only adjusts the pH value but also effectively reduces the cross-sectional resistance of the electrode after curing, thereby improving the conductivity of the cured substrate 521.

[0268] In this embodiment, the ratio of alkaline reagent added is in the range of 30% to 70%, wherein the alkaline reagent can be KOH, NaOH, etc., and the acidic reagent can be polyacrylic acid, etc.

[0269] In some embodiments, when the voltage output component 51 outputs a first voltage to the electrode component 52, the first voltage is directly transmitted to the first conductive fiber 5221 via the conductive structure 58.

[0270] In some embodiments, when the voltage output component 51 outputs a first voltage to the electrode component 52, an instantaneous potential difference is formed between the first conductive fiber 5221 and the second conductive fiber 5222. Under the action of the conductive component, a current is formed in the solidified substrate 521, so that the circuit formed between the first conductive fiber 5221 and the second conductive fiber 5222 is connected.

[0271] The first conductive fiber 5221 and the second conductive fiber 5222 are connected to a first voltage to form an electric field at the emitting end of the electrode component 52 and ionize the moisture in the air absorbed by the electrode component 52.

[0272] In some embodiments, refer to Figure 17 When the voltage output component 51 outputs the first voltage to the electrode component 52, an instantaneous potential difference is formed between the second conductive fiber 5222 and the first conductive fiber 5221. In the solidified matrix 521 between the first conductive fiber 5221 and the second conductive fiber 5222, conductive ions 528 move towards the first conductive fiber 5221 and electrons move towards the second conductive fiber 5222. A circuit is formed between the first conductive fiber 5221 and the second conductive fiber 5222 so that all conductive fibers 522 can be connected to the first voltage, providing a high voltage for the ionization and absorption of moisture in the air by the electrode component 52.

[0273] Reference Figure 18 Taking potassium ions as an example, when a negative high voltage is applied to the conductive structure 58, a potential difference is instantaneously formed between the conductive structure 58 and the nearby conductive fiber 5223411A. In the solidified matrix 521 between the two, electrons move towards the conductive fiber 3411A, and K+ moves towards the pointed structure, forming a circuit connection. The conductive fiber 3411A is connected to the negative high voltage.

[0274] Similarly, a potential difference is instantaneously formed between conductive fiber 3411A and conductive fiber 3411B. In the solidified matrix 521 between the two, electrons move towards conductive fiber 3411B and K+ moves towards conductive fiber 3411A, forming a circuit connection. Conductive fiber 3411B is connected to a negative high voltage.

[0275] Similarly, the outermost conductive fiber 5223411Z is connected to the negative high voltage.

[0276] In the above embodiments, the cross-sectional resistance of the electrode component 52 can be less than 250 ohms, which enables all conductive fiber bundles in the electrode component 52 to form an effective local electric field and effectively release water ions.

[0277] In some embodiments, the conductive component is a conductive material 527.

[0278] In some embodiments, refer to Figure 23 In this context, the conductive material 527 is a spherical conductive material 527. Examples include carbon powder, graphene powder, etc.

[0279] In some embodiments, refer to Figure 24 The conductive material 527 is a short rod-shaped conductive material 527. Examples include short carbon fibers, etc.

[0280] In some embodiments, the conductive material 527 is introduced by adding the conductive material 527 during the preparation of the cured substrate 521, so that the conductive material 527 is suspended or floated inside the cured substrate 521.

[0281] After the electrode component 52 is energized, the conductive material 527 is used to achieve an electrical connection between the conductive fibers 522.

[0282] The conductive material 527 in the cured matrix 521 and the carbon fiber conduct electricity in a coordinated manner, which can effectively reduce the cross-sectional resistance of the cured matrix 521 and improve the conductivity of the cured matrix 521.

[0283] Reference Figure 21-22 Conductive material 527 forms a conductive material 527 layer within the cured substrate 521, and the thickness of the conductive material 527 layer is defined as H. 导 The diameter of conductive fiber 522 is defined as D. 纤维 , where H 导 >5×D 纤维 This ensures effective contact between the conductive materials 527 within the conductive material 527 layer, resulting in good conductivity within the cured substrate 521.

[0284] In this embodiment, a conductive material 527 layer is added to the cured substrate 521. This is achieved by adding a material that does not chemically react with the cured substrate 521 and has good electrical conductivity to the solution during the preparation of the cured substrate 521, while the cured substrate 521 is in a solution-mixed state.

[0285] During the curing reaction of the substrate 521 and the conductive fiber 522, the electrode component 52 is placed vertically (or nearly vertically, with the electrode rod at an angle of 60° to 120° to the horizontal plane). After the curing reaction is completed, the filled conductive material 527 will be deposited into a layer, namely the conductive material 527 layer. The small particles in the conductive material 527 layer are connected to each other and can contact and connect with the conductive components and the conductive fibers 522 in the electrode component 52 to form good conductivity.

[0286] In some embodiments, the position of the conductive material 527 layer in the electrode rod is not limited to the bottom. Since the conductive material 527 has a certain gravity, the position of the conductive material 527 in the cured substrate 521 can be controlled by controlling the placement of the electrode component 52, the density of the conductive material 527, and the quantity of the conductive material 527 during the preparation of the electrode component 52.

[0287] In some embodiments, if the density of the conductive material 527 is less than the density of the cured matrix 521, the conductive material 527 may float or suspend inside the cured matrix during the curing reaction, and thus the conductive material 527 layer will be formed on the upper part of the electrode rod.

[0288] In this embodiment, refer to Figure 25When conductive material 527 is formed at the emitter end of the cured substrate 521, a conductive material 527 layer is formed within the cured substrate 521, and the thickness of the conductive material 527 layer is defined as H. 导 The height of electrode component 52 is H 棒 The height of conductive structure 58 is H. 电 Then H 导＞ H 棒 -H 电 This ensures that the conductive material 527 layer can effectively connect the pointed structure or conductive structure 58 to each conductive fiber 522 within the electrode component 52, thereby ensuring that the electric field output by the electrode component 52 meets the ionization requirements.

[0289] In some embodiments, if the density of the conductive material 527 is approximately the same as the density of the cured matrix 521, then the conductive material 527 is uniformly dispersed within the cured matrix, and the conductive material 527 layer has no clear boundary. In this case, H can be considered as 导 =H 棒 .

[0290] In some embodiments, the conductive material 527 layer is achieved by adding a blend of raw materials that can improve the conductivity of the cured substrate 521 during the formation of the cured substrate 521.

[0291] In some embodiments, the conductive structure 58 is configured as a pointed structure, which is partially or completely submerged in the electrode component 52 so that the electrode component 52 is connected to a first voltage.

[0292] In some embodiments, the pointed structure is inserted from the bottom of the electrode component 52 and partially submerged in the electrode component 52 to ensure effective connection between the pointed structure and the conductive fiber 522 and the cured substrate 521.

[0293] In some embodiments, the periphery of the pointed structure is beveled to facilitate insertion into the electrode component 52 and tight connection with the conductive fiber 522 and the cured substrate 521, ensuring a stable input of the first voltage.

[0294] In this embodiment, the pointed structure is partially embedded in the electrode component 52 to avoid affecting the overall strength of the electrode component 52.

[0295] Reference Figure 19 In the diagram, the diameter of electrode component 52 is defined as D_rod, and the height of electrode component 52 is defined as H_rod.

[0296] Reference Figure 20 In the text, the height of the pointed structure is defined as H. 针 The height of the needle tip of the pointed structure is defined as H. 针尖 The diameter of the pointed structure is defined as D. 针The diameter of conductive fiber 522 is defined as D. 纤维 The average distance between conductive fibers 522 is defined as I2, and the closest distance between conductive fibers 522 and the pointed structure is defined as I1.

[0297] In some embodiments, the diameter relationship between the conductive fiber 522, the pointed structure, and the electrode component 52 is: D 纤维 <D 针 <D 棒 / 3.

[0298] By setting D_needle < D_bar / 3, the diameter of the pointed structure is prevented from being too large during the process of the pointed structure being inserted into the electrode component 52, which could cause the electrode component 52 to crack or affect the overall strength of the electrode component 52.

[0299] By setting D fibers < D needles, not only can the requirements for the pointed structure be reduced, but the pointed structure can also connect multiple conductive fibers 522 at the same time to ensure the stability of the first voltage output of the local conductive fiber 522.

[0300] In some embodiments, the conductive fibers 522 are uniformly dispersed longitudinally, and the average distance between each fiber and its nearest surrounding fiber is I2, where I2 < D. 针 Furthermore, it should be ensured that the distance between conductive fibers 522 (more than 50% of which are conductive fibers) and the nearest surrounding fibers is less than 2 × I², so as to ensure that the cured substrate 521 has good electrical conductivity under the action of potassium ions, etc.

[0301] In some embodiments, to ensure sufficient contact between the pointed structure and the cured substrate 521, and to ensure ease of insertion of the pointed structure into the cured substrate 521, the tip of the pointed structure should be designed as a sharp needle tip. 针尖 >2×D 针 Therefore, the conductive fibers 522, which are not directly connected by the pointed structure, conduct electricity through potassium ions in the cured matrix 521 to connect to the first voltage.

[0302] In some embodiments, to ensure the contact area between the pointed structure and the cured substrate 521, and to ensure the fixing effect of the pointed structure on the electrode rod and the stability of the connection, the pointed structure should be fully inserted into the cured substrate 521. 棒 / 5 <H 针 <H 棒 .

[0303] In some embodiments, the charged microparticle water generator 5 further includes a connecting member 59. The connecting member 59 is disposed at the bottom of the electrode member 52 and is connected to the conductive structure 58 to connect the voltage output member 51 and each conductive fiber 522, so that a first voltage is conducted to the conductive fibers 522. This ensures stable installation of the conductive structure 58.

[0304] In some embodiments, the connecting member 59 is made of metal. Effective contact is achieved between the conductive fiber 522 and the end face of the connecting member 59 near the electrode member 52, preventing incomplete connections.

[0305] In other embodiments, the connecting component 59 may also be configured as conductive adhesive.

[0306] In this embodiment, the ratio of the connecting component 59 to the cured substrate 521 should be less than 1:2 to minimize the loss of the moisture absorption capacity of the electrode structure.

[0307] In some embodiments, the conductive structure 58 includes a connecting member 59 disposed at the bottom of the electrode member 52 and connected to the tip structure to improve the stability of the tip structure installation.

[0308] The connecting component 59 is used to connect the negative high-voltage conductor 60 and each conductive fiber 522. The negative high-voltage electricity is conducted to each conductive fiber 522.

[0309] In some embodiments, the charged microparticle water generator 5 includes a high-voltage conductor 60. One end of the high-voltage conductor 60 is connected to a voltage output component 51, and the other end of the high-voltage conductor 60 is connected to a conductive structure 58 to deliver a first voltage output by the voltage output component 51 to the conductive fiber 522.

[0310] In some embodiments, one end of the high-voltage wire 60 is connected to the voltage output component 51, and the other end of the high-voltage wire 60 is connected to the connection component 59.

[0311] In some embodiments, refer to Figure 27 Several conductive structures 58 are provided. These conductive structures 58 are combined with connecting components 59. The example in the figure shows a pointed structure. The combination of the pointed structure and the connecting component 59 serves both to conduct electricity and to provide a fixed connection.

[0312] In some embodiments, the diameter of the connecting member 59 is the same as the diameter of the pointed structure.

[0313] In some embodiments, the diameter of the connecting member 59 is slightly larger than the diameter of the pointed structure.

[0314] Due to the increased number of conductive structures 58, compared to a single conductive structure 58, the height and diameter of the conductive structure 58 can be reduced without compromising conductivity between the conductive structure 58 and the conductive fiber 522. This results in a more secure and reliable contact between the conductive structure 58 and the electrode component 52, while also making it easier for workers to install and press the electrode component 52.

[0315] In some embodiments, refer to Figure 26 The conductive structure 58 includes a metal snap fastener 61. The metal snap fastener 61 is included around the electrode component 52, such that the diameter of the electrode component 52 wrapped with the metal snap fastener 61 is smaller than that of the electrode component 52 not wrapped with the metal snap fastener 61, so as to shorten the distance between each conductive fiber 522; and the metal snap fastener 61 is in contact with the conductive fibers 522 on the surface of the electrode component 52.

[0316] When the voltage output component 51 transmits the first voltage to the conductive fiber 522 located on the surface of the electrode component 52 through the conductive structure 58, an instantaneous potential difference is formed between the conductive fiber 522 located on the surface of the cured substrate 521 and the conductive fiber 522 located inside the cured substrate 521. Under the action of the conductive component, a current is formed in the cured substrate 521, so that a circuit connection is formed between the conductive fiber 522 located on the surface of the cured substrate 521 and the conductive fiber 522 located inside the cured substrate 521.

[0317] The conductive fibers 522 located on the surface of the cured substrate 521 and the conductive fibers 522 located inside the cured substrate 521 are connected to a first voltage to form an electric field at the emitting end of the electrode component 52 and ionize the moisture in the air absorbed by the electrode component 52.

[0318] In the above embodiment, the high-voltage wire 60 is bundled together with each conductive fiber 522 by metal deformation and extrusion, which shortens the distance between the conductive fibers 522, reduces the resistance value between each conductive fiber 522, and conducts the negative high voltage to each conductive fiber 522.

[0319] The high-voltage wire 60 is fixedly connected to each conductive fiber 522 by the metal buckle 61 in this embodiment, which can omit the pointed structural components and pointed structural connection points.

[0320] In some embodiments, when the conductive component is a conductive ion 528, when the voltage output component 51 outputs a first voltage to the electrode component 52, an instantaneous potential difference is formed between the conductive fibers 522 located on the surface of the cured substrate 521 and the conductive fibers 522 located inside the cured substrate 521. In the cured substrate 521 between the conductive fibers 522 located on the surface of the cured substrate 521 and the conductive fibers 522 located inside the cured substrate 521, the conductive ions 528 move towards the conductive fibers 522 located on the surface of the cured substrate 521, and the electrons move towards the conductive fibers 522 located inside the cured substrate 521. A circuit connection is formed between the conductive fibers 522 located on the surface of the cured substrate 521 and the conductive fibers 522 located inside the cured substrate 521, so that all the conductive fibers 522 can be connected to a high voltage to provide a high voltage for the ionization of moisture in the air absorbed by the electrode component 52.

[0321] In some embodiments, the water ion generator further includes a voltage output component 51. The voltage output component 51 is connected to the electrode component 52 to provide a first voltage to the electrode component 52.

[0322] The moisture in the electrode component 52 is excited by the first voltage to form charged microparticle water. The charged microparticle water carries a charge and hydroxyl radicals generated by the ionization of water, which improves the air purification effect.

[0323] A power switch is electrically connected between the voltage output component 51 and the electrode component 52. The power switch is used to control the opening or closing of the circuit between the electrode component 52 and the voltage output component 51, thereby controlling the electrode component 52 to be energized or de-energized. This configuration allows the charged microparticle water generator 5 to be controlled to operate by powering on or off via the power switch, which is simple and convenient.

[0324] In some embodiments, the voltage output component 51 may be electrically connected to the control board of the indoor unit of the air conditioner 100.

[0325] The voltage output component 51 has a negative high voltage output terminal and a ground electrode. The negative high voltage output terminal is connected to the electrode component 52 through a wire to provide a negative voltage of 0.3KV to 3.5KV, so that a negative high voltage electric field is formed between the electrode component 52 and the ground electrode, thereby causing the electrode component 52 to generate hydroxyl charged microparticle water and negative ion charged microparticle water.

[0326] Reference Figure 28 The voltage output component 51 includes an oscillation circuit. The oscillation circuit includes a triangular wave output circuit 512. The input terminal of the triangular wave output circuit 512 is used to connect to an external power supply. The output terminal of the triangular wave output circuit 512 is used to output a triangular waveform with a stable frequency.

[0327] The external power supply is a 12V DC power supply, which can be directly provided by the indoor unit's control board, eliminating the need for an external power source connection and simplifying the structure. After connecting the power input line to the external power supply, the 12V DC power is input to the oscillation circuit.

[0328] Reference Figure 28 The oscillation circuit also includes a PWM signal output circuit 513, which converts the received triangular wave into a PWM signal and outputs it. Under the control of the stable PWM signal, the secondary coil of the transformer 517 outputs a high voltage with a stable frequency to supply a stable high voltage to the electrode component 52, ensuring the ion release concentration.

[0329] Compared to high-voltage generating circuits based on transformer feedback circuits, which suffer from unstable oscillation frequencies, the oscillation circuit in this embodiment can achieve accurate control and adjustment of the oscillation frequency by adjusting components. This ensures stable ion release and enables control over the amount of ion released.

[0330] In some embodiments, the frequency of the high voltage output can be adjusted by regulating the frequency of the triangular waveform output by the triangular wave output circuit 512, thereby influencing the amount of ion release.

[0331] In some embodiments, when a high amount of ion generation is required, increasing the oscillation frequency increases the number of pulses generated per unit time; a higher number of pulses results in a corresponding increase in the amount of ion generation. Refer to Figures 32-33 for the voltage pulse waveforms corresponding to different oscillation frequencies. Figure 32 In this process, the oscillation frequency is low, the number of pulses is small, and the amount of ions produced is relatively small. Figure 33 In this process, the oscillation frequency is high, the number of pulses is high, and the amount of ions produced is relatively high.

[0332] In some embodiments, different frequencies of the PWM signal result in different numbers of negative high-voltage pulses generated after passing through the rectifier circuit. In some embodiments, when the output voltage amplitude on the secondary side of transformer 517 is the same, a higher oscillation frequency results in more negative high-voltage pulses generated per unit time, and thus more water ions generated. Conversely, a lower oscillation frequency results in fewer negative high-voltage pulses generated per unit time, and thus fewer water ions generated.

[0333] In addition, considering the limitations of module structure and component performance, the size of high-frequency transformers cannot be too large, so their step-up ratio cannot be too large, and therefore the step-up ratio is subject to certain limitations.

[0334] With a fixed external power supply, the amplitude of its output voltage is also limited. Due to limitations in component specifications and performance, the circuit's oscillation frequency is also restricted. Therefore, after determining the amount of water ions released, considering both module size and component performance, a suitable transformer 517 step-up ratio and readily available mass-produced components are chosen for the circuit design.

[0335] In some embodiments, when the required ion production is low, reducing the oscillation frequency will decrease the number of pulses generated per unit time, and the ion production will decrease accordingly.

[0336] In the above embodiments, by adjusting the circuit parameters, the voltage output component 51 can output voltages with different amplitudes and frequencies, thereby controlling the amount of water ions released.

[0337] In some embodiments, the voltage output component 51 includes a drive circuit 514. The drive circuit 514 is used to compensate for the disadvantage that the comparator has poor load-carrying capacity and cannot directly drive the switching component.

[0338] The drive circuit 514 includes a push-pull circuit. The input of the push-pull circuit is connected to the PWM signal output circuit 513, and the output of the push-pull circuit outputs the amplified PWM signal.

[0339] The voltage output component 51 includes a switching device 515. In some embodiments, the switching device 515 includes a MOSFET U2. The MOSFET U2 is switched at a high frequency using a PWM signal.

[0340] In some embodiments, the switching device 515 may also be configured as an IGBT or other switching device.

[0341] The voltage output component 51 includes a boost circuit for boosting the output voltage to achieve the required ionization electric field strength for the electrode component 52.

[0342] The boost circuit includes a transformer 517. Its primary winding is connected to the output terminal of the switching device 515, and its secondary winding is connected to the electrode component 52. The transformer 517 is used to receive pulsed voltages, boost them, and then output them.

[0343] The MOSFET U2 generates a pulsed voltage on the primary side of the transformer 517. This pulsed voltage is boosted by the high-frequency transformer 517, resulting in a high voltage on the secondary side of the transformer 517. This high voltage is applied to the electrode component 52 to generate negative ions.

[0344] In some embodiments, refer to Figure 28 The high-voltage output circuit includes a rectifier circuit 519. The high voltage generated on the secondary side of the transformer 517 is rectified by the rectifier circuit 519 and applied to the electrode component 52 to generate negative ions.

[0345] Reference Figure 29 In some embodiments, the boost circuit includes at least one voltage multiplier circuit 518 to achieve voltage multiplication. In this embodiment, the voltage can be boosted twice by the voltage multiplier circuit 518 before being applied to the electrode component 52.

[0346] Reference Figure 29 In this circuit, the boost circuit includes a diode voltage multiplier circuit 518. At the same oscillation frequency, the output voltage of the electrode component 52 can be adjusted by changing the boost ratio of the transformer 517 or the number of stages in the voltage multiplier circuit 518. Under the same circuit structure, the higher the voltage of the electrode component 52, the greater the ion release.

[0347] Reference Figures 30-31 The figure shows the test waveforms of electrode component 52 under different boost ratios.

[0348] In some embodiments, increasing the oscillation frequency increases the number of pulses generated per unit time, resulting in a higher number of pulses and a corresponding increase in ion production. Conversely, decreasing the oscillation frequency reduces the number of pulses generated per unit time, leading to a lower number of pulses and a lower ion release.

[0349] MOSFET U2 switches at high frequency under the control of the PWM signal. The power supply returns to ground through the primary side of transformer 517 and MOSFET U2. During the switching process of MOSFET U2, the generated pulse voltage is boosted by transformer 517 and then output as a high voltage on the secondary side. Due to the rapid switching of MOSFET U2, high-frequency oscillations are generated on the primary side of transformer 517.

[0350] In some embodiments, when the oscillation frequency remains constant, increasing the step-up ratio of transformer 517 increases the peak voltage generated by the secondary winding of transformer 517, resulting in a larger output voltage acting on electrode component 52 after rectification, and thus an increase in the amount of water ions released.

[0351] In some embodiments, the voltage is boosted by a voltage multiplier circuit 518, which increases the peak output voltage on the electrode component 52 to increase the amount of water ions released.

[0352] In some embodiments, by reducing the step-up ratio of transformer 517 or by eliminating the voltage multiplier circuit, the peak output voltage on electrode component 52 is reduced, thereby reducing the release of water ions. For example... Figures 30-31 The image shows a comparison of the waveforms of electrode component 52 under different step-up ratios of transformer 517, where V2 <V1。

[0353] In some embodiments, the voltage output component 51 includes a resonant circuit 520 to reduce the impact of resonance on high voltage.

[0354] In some embodiments, refer to Figure 34It can also generate a stable PWM signal through the MCU. The frequency of the PWM signal can be set by the program as needed. The PWM signal controls the drive circuit 514 to drive the MOSFET U2 to work.

[0355] Compared to the high-voltage output circuit based on the feedback oscillation circuit of the transformer 517 in related technologies, the voltage output component 51 in this embodiment has a stable oscillation frequency and can accurately control and adjust the oscillation frequency by adjusting the resistance value of the components, thereby achieving accurate control of the ion release amount. At the same time, a resonant circuit 520 is designed for the oscillation generated by the high-frequency switch, so that the high voltage output by the voltage output component 51 is not affected by the resonance.

[0356] In some embodiments, the frequency, number of pulses, and magnitude of the first voltage of the PWM signal can be controlled according to the detected indoor air conditions or pollution levels in order to control the ion release concentration.
